The relationship between electrical and structuralcharacteristics of polycrystalline HfO2films has been investigated by conductive atomic force microscopy under ultrahigh vacuum conditions. The results demonstrate that highly conductive and breakdown (BD) sites are concentrated mainly at the grain boundaries (GBs). [...]
